    Study Notes

    Microorganisms and Fermentation

    • Microorganisms, or microbes, can only be seen under a microscope.
    • Fermentation is an anaerobic process converting sugars into alcohol, gases, and organic acids using bacteria, mold, or yeast.
    • Foods produced through fermentation include beer, bread, and cheese, while orange juice is not derived from this process.

    Historical Figures in Microbiology

    • Hippocrates is known as the "father of Western medicine."
    • Antonie van Leeuwenhoek was the first to observe "animalcules" under a microscope.
    • Marcus Terentius Varro suggested that swamps might contain small, disease-causing organisms.
    • Thucydides is recognized as the father of scientific history.
    • Ötzi the Iceman is thought to have had Lyme disease.

    Taxonomy and Nomenclature

    • Taxonomy involves classifying, describing, identifying, and naming living organisms.
    • Binomial nomenclature assigns a unique two-part name (genus and species) to organisms.
    • A phylogenetic tree illustrates relationships among species through common ancestors.
    • Proteins are incorrect according to Linnaeus's original king: they were not a part of his taxonomy system.

    Domains and Classification

    • Woese and Fox's phylogenetic tree does not include Plantae as a domain.
    • Bergey's Manual of Determinative Bacteriology is the standard reference for identifying bacteria.
    • Organisms are classified into three domains: Archaea, Bacteria, and Eukarya.
    • Prokaryotes, which include Archaea and Bacteria, lack membrane-bound nuclei.

    Definitions of Organisms

    • Archaea are found in diverse environments without being human pathogens.
    • Eukaryotes consist of algae, protozoa, fungi, and helminths.
    • Algae are photosynthetic, either unicellular or multicellular.
    • Protozoa are motile, unicellular organisms.
    • Microscopic fungi include molds and yeasts.

    Parasitic and Acellular Microorganisms

    • Helminths are multicellular parasitic worms, studied in microbiology due to microscopic eggs and larvae.
    • Viruses, which are acellular, need a host for reproduction.
    • Algae are the only photosynthetic microorganisms listed as answer options in specific questions.

    Various Microbiology Subfields

    • Prokaryotic microorganisms include cyanobacterium, while yeast is a type of fungal microorganism.
    • Virology is the study of viruses.
    • Botany is not considered a subfield of microbiology, while bacteriology, clinical microbiology, and virology are.

    Pathogens

    • A pathogen is defined as any disease-causing microorganism.
    • Multicellular parasitic worms are referred to as helminths in microbiological studies.
